Yes, given the fact that at least three groups of vertebrates evolved powered flight, it is ASB to posit a world without bats, birds, pterodactyls, etc. Evolution of flying animals appears to be inevitable. However, it might not be ASB to posit a world in which they all became extinct by the time humans evolved.
This would probably affect the human desire for flight and limit a belief that machines could be built to do this. Early inventors would model their efforts on study of insects and gliding creatures such as flying fish, flying squirrels, etc. You might see more designs with four flapping wings or helicopter-like things. Oddly, the absence of flapping large vertebrates might help. Rather than assuming that the key to flight was flapping wings, inventors might focus more efforts on understanding how fish and squirrels glide. This could actually accelerate an understanding of flight and and not waste centuries trying to create flapping wings.
